CxxTest编译，缺少主 [英] CxxTest compiling, missing main

问题描述

我使用CxxTest进行单元测试。我跟着文档。

I am using CxxTest for unit testing. I followed the docs.

我执行的第一个命令是：

First command I executed was:

cxxtestgen --error-printer -o runner.cpp MyTestSuite1.h

命令的输出为 .cpp 文件。

根据文档，下一个命令应该是：

According to the documentation, next command should be:

g++ -o runner -I(location_of_the_cxxTest_headers) runner.cpp

但我无法执行它，我收到关于缺少入口点的错误。换句话说， runner.cpp 缺少main。

but I am unable to execute it, I am receiving the error about missing entry point. In other words, runner.cpp is missing main.

CxxTest包含的测试文件也会发生同样的情况。

Same thing happens with the test files included with CxxTest.

我正在运行Windows 8.1。

I am running Windows 8.1.

我的问题被标记为重复，但我没有找到解决方案在另一个问题。我不是构建一个GUI应用程序。问题是关于CxxTest，它甚至开始没有 main（）函数？

My question is marked as a duplicate, but I didn't find solution in the another question. I am not building a GUI application. Question is about CxxTest and how does it even start without a main() function? Where is the entry point?

推荐答案

我在查看python脚本 cxxtestgen后发现了一个解决方案。 py ，用于生成 runner.cpp 。在 writeMain（output）函数的开头有一个if语句，它在输出文件中写入 main

I have found a solution after looking at a python script cxxtestgen.py which is used to generate runner.cpp. There is an if statement at the beginning of a writeMain(output) function which writes main function in an output file:

if not (options.gui or options.runner):
       return

两个选项中至少有一个 - runner = CLASS 和<$ c从测试套件生成输出文件时，需要$ c> - gui = CLASS 。添加一个选项后，一切运行良好。

At least one of the two options, --runner=CLASS and --gui=CLASS is required when generating output file from test suites. After adding one option everything runs fine.
